How different between MTBF and MTBF rating? I heard from someone the MTBF rating is more accurate than MTBF. I'm very confuse.

Please let me understand and how to calculate.

Thanks you

I'm not aware of the term "MTBF Rating"? What is it?

I really don't know more about MTBF Rating, I just ask to ensure the term of use MTBF that enough to represent equipment reliability.

MTBF is the first term after failure rate. Reliability should be properly described by probability density function, probability distribution function, hazard rate function and cummulative function. Can SAP provides these informations?

I think, SAP could not provide these analysis data but only event date to calcurate TTF that lead to calculation Beta and Eta for weibull analysis.

Now, I try to use some demo software to demonstrate unreliability vs time, failure rate, pdf, cdf and so on.

And being feasibility study about software to illustrate our system reliability go to optimization and improvement.

If you configure the formulae in SAP, isn't it possible to do so?

Josh, I'm not sure SAP can configure to calculate System Reliability. Do you have experience?
